LUBRICATING MATERIAL AND METHOD 0F MANUFACTURING y specificati@ of Leiters Patent.

Patented sept. 5', 1911.

Application led April 15, H11. Serial No. 621,283. i

.I Se it knownthat `I, HENRY P. 'Wm'.m, a citizen of the United States, residing 'at Kalamazoo, Michigan, have invented certain new and useful Improvements in Lubricating Materials and Methods of Manufacturing the Same, of which the following is 'a specification.

This invention relates to improvements in lubricating materials and methods of manufacturing the same. j rIhe object of the invention is to provide an efficient retaining means for a graphite, or other solid lubricant material, such as talc or mica in the form of powder or a flaky powder, ing surface which can be readily inserted in place, as for the packing of a piston rod or valve stem, bearing.

A further object of my invention is to provide an improved method of manufacturing such a lubricating material.

Objects pertaining to details and economies will definitely appear from the descripby the devices and means described in the following specification.

pointed out in the claims.

The means and methods adopted by me for carrying out my invention are, so far as practical, illustrated in the accompanying dra-wing, forming a part of this specification, in which,-

Figure I illustrates a plain sheet of metal foil.. Fig. II is a sheet of metal foil after it has been crumpled according to my method, the left-hand end portionof the same having been coated with oil, and the right-hand end portion illustrated as coated with graphite or other solid lubricant inl addition. Figs. III and IV are cross sectional views of the structure appearingin Fig. II, taken on lines 3 8 and 4-4 respectively, Fig. -III indicating the `oiled part and Fig. IV the cross section ofthe part loaded with graphite or solid lubricant in addition thereto. Fig. V illustrates the crumpled sheet rolled into a 'scrolL Fig. VI is an enlarged detail cross-sectional view of the structure appearing in Fig. V. Fig.

V-II shows the structure appearing in Fig. V after it has been somewhat compressed into bar forni. VIII illustrates a cross to preserve an efficient bear-y ort-he lining of a journal lI`he invention is clearly deni'ined andy :section of the bar seen in Fig. VII, illustrating the distribution of the metal and lubricating material. Fig. IX is a detail -view of a journal bearing lined with the packing materiahthe particular example being the bearing in a trolley wheel. Fig. X

is a view of my improved packing as ak gasket in a stuffing box for a piston rod.

In the drawing, the'sectional views are taken looking inthe arrows at the ends of the section lines, and similar numerals of reference refer tosimilar parts throughout the several views. l

Referring to the numbered parts of the drawing, l illustrates a flat, rectangular sheet of metal foil, of smooth and even texture. Fig. yII illustrates the sheet) after it 'has been crumpled. The surface is thus rendered irregular, the'dimension of the sheet being reducedlabout the proportion` I have illustrated, the same being taken fromphotographs to show the comparative size and reduction. When the sheet is in the flat, as seen in Fig. I, it is evenly and thoroughly coated with a lubricating oil of the desired consistency. A high grade lire test of engine oil is desirable for use with graphite. For some purposes, a heavy oilv is used, and for others, a light coating is all that is required. After thetl sheet is thus coated and crumpled, las seen in II, itl

is treated to what I denominate av bath of.

direction of the little powdered flake graphite.v This step of the process is accomplished either by dredging the surface over with graphite, or by 'covering the crumpled. sheetl with a mass of the powder. In practice, y

use a tray or pan with flake graphite with- 4in the same, and bury the sheet in the graphite, turning the sheet over and over until the same ois coated. The crumpled surface, on it, lis indicated at 2 in Fig. II, and crumpled surfacecoated with the graphite is indicated at 3 in Fig. II. -It will be seen by referring to Figs. III and IV, how irregular the surface is made, and how completely it is coated or loaded with the graphite 4C. After the crumpled sheet has been thoroughly coated with the graphite or other similar inateri al, or lubricating powder, the same is rolled up into'a scroll, as `appears in Fig. V, the cross-sectional View appearing in Fig. VI. B y thus rolling up the sheet over which the graphite or other lubricating material thoroughly and completely with the oil the I find it desirableto Y is distributed, the same ifs 'about the proportion indicated in Fig. VII,

which I denominate semi-compressed straps.

An enlarged' cross ysectional' View of fthe structure of Fig. V-II appears in` Fig. VIII, giving an idea of the appearance of the material.l These semi-compressed-straps can be very readily handled wit-hout injury, and are very conveniently put into packages and shipped for use. They are handled and put in place .as ordinary packing material by being bent around and crammed into place by a suitable calking,

tool when usedin ,journal' bearings. The material vis shown in a journal bearing 5 in Fig. IX, the same vhaving been forced into4 position, as indicated. I show it in a stuling box for a piston rod forming' the gasket 6 inFig. X. The. material is especially desirable` for such use. It requires ,no ramming or tamping to form a gasket. Screwing or drawingup the glandis sulli-v cient to conform and compress the same in place j y Great advantage results from rolling the material into a scroll. The material will be quite desirable and eiiicient if the crumpled ,sheet be merely compressed, but the whole vf'mass would notbe so effectively retained. The metal foil should be of suitable composit-ion for the service intended. For jour- `nals, a soft metal only is needed. Where a "piston rod or other packing is required, alloys that will resist the heat are made use .-of. Low steam pressure packing up to 150 lbs. pressure need not differ from the journal fpacking, and above that pressurealloys of considerable -heat resistance are required. Smooth rolled foil is most ldesirable for the metal sheet, but metal in approximate sheet form, when crumpled, is quite efficient.

' I wish my appended claims to be understood as claiming the broad feature, and also the specific devices, as the state of the art warrants.

Having thus described my invention, what I claim as new and desire to secure by Letters 'Patent is;

1. A packing 'material consisting `of crumpled sheet metal coated with oil and powdered lubricant formed into a scroll and compacted-together, as specified.

tamping or ramming packing 'material consisting 'crumpled sheet metalj coated'with oil and. powdered -graphite formed into a scroll and compacted together, as specied.

3. A packing' material consisting of crumpled sheet -metal coated with oil and 6i powdered lubricant folded and compacted together, as specified.

4.-' A packingl material consisting of crumpled sheet metal coated with oil and powdered graphite folded and compacted together, as specified.
